Abstract

One or more portions (221) of a database (220) which a primary server (106) uses to process client requests are duplicated (211) on one or more supplemental servers (105). As the clients demand for service increases and the processing load on the primary server becomes excessive (400), the primary server automatically off-loads the processing of those portions of the client requests that require one or more of the duplicated portions onto the supplemental servers by substituting (402) a secondary page (253) or a secondary object in its database that points to the one or more duplicated portions in the supplemental servers for a corresponding primary page (252) or a primary object in its database that points to the one or more duplicated portions in its database. The supplemental servers then serve the portions of the client requests that require the one or more of the duplicated portions. As demand for service decreases and the primary server becomes underloaded (404), it automatically restores (406) the primary page or the primary object in its database and resumes serving the entire client requests.
